Working boot firmware image for the Apple iMac A1312, supplied as a 6.66 MB RAR archive. The name gives only the model number and a fully working claim, with no logic board number or revision, so the exact board it came from is not stated. Such a dump is written to the SPI flash chip with a programmer to revive a machine that will not boot due to corrupted firmware. Always back up the existing chip first and make sure the image size matches the flash capacity on your board.
